Problems deleting folder in Mail directory

So in playing around with the email folder (attempting to make a backup and then restore it) via SSH I ended up with a spare folder that has a folder under it, and I can not delete them to save my life.

this is in /private/var/mobile/library/mail and I just can't seem to delete the spare. I've tried changing the permissions, even set recursively, and I just can't get SSH to ax them.
